Answer:
The answer to your question is 12 hydrogen atoms
Step-by-step explanation:
Chemical equation
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
To know how many atoms of each element are in each side of the reaction, we must multiply the coefficient at the beginning of the compound by the number after the element.
Example
For Hydrogen
Coefficient for H₂O = 6
Number after H = 2
Multiply these numbers = 6 x 2 = 12 atoms of hydrogen
